How to Integrate SeaText AI via JavaScript: Step-by-Step Setup

Direct Answer: The Integration Steps

Integrating SeaText AI via JavaScript takes four core steps. First, sign up for a SeaText account and get your API key. Second, copy the JavaScript snippet from your dashboard. Third, paste that snippet into your website's HTML. Fourth, visit your site to activate the connection, then choose which AI agents to turn on.

The script is inert until you activate it, so your site's content stays unchanged during setup. You can complete the basic installation in under a minute, but activation and verification add a few more minutes.

Prerequisites Before You Start

You need three things before adding the script:

• A SeaText AI account. If you don't have one, create it first. Each account is linked to a single primary URL.
• A valid, real domain. Development URLs like localhost are restricted for security reasons. Use your production domain or a real staging domain.
• Access to your site's HTML. You need to edit the page template, theme, or use a plugin that allows custom JavaScript.

If you use WP Engine, download the WP Engine plugin that lets you add custom JavaScript to your pages. Install it and apply it across all your pages.

Step 1: Create Your SeaText Account

Go to the SeaText website and create an account. The account is tied to one primary URL, so use the domain where you plan to run SeaText. If you need SeaText on multiple domains—for example, a development domain and a production domain—create separate accounts for each domain.

After signing up, log in to your dashboard. You'll find the JavaScript code in the General Integration section.

Step 2: Copy the JavaScript Snippet

In your SeaText dashboard, navigate to the General Integration page. You'll see a JavaScript code block. Copy the entire snippet exactly as provided. Do not modify it.

The snippet is a script tag that loads SeaText's AI engine on your site. It remains inactive until you activate it from the dashboard, so pasting it won't change your live content immediately.

Step 3: Paste the Script into Your HTML

Paste the script into your website's HTML. The best practice is to place it just before the closing </body> tag so it loads after your main content. This prevents the script from blocking page rendering.

How you add it depends on your platform:

• Custom HTML site: Edit your template file and paste the script before </body>.
• WordPress: Use a header/footer plugin or your theme's custom script area. On WP Engine, use their custom JavaScript plugin.
• Shopify, Webflow, or other builders: Look for a custom code or integrations section in your site settings.

Apply the script across all pages where you want SeaText to run. If you only add it to one page, SeaText will only work on that page.

Step 4: Activate the Connection

After pasting the script, visit or refresh your website several times. Stay on a page for at least 40 seconds each time. This tells SeaText's system that the script is live and links it to your account.

Then wait at least five minutes. Go back to your SeaText dashboard and look for your website name next to the SeaText logo at the top of the page. If you see it, your site is connected. If you don't see it after 10 minutes, contact SeaText support—there may be an installation issue.

Step 5: Activate AI Agents

Once your domain is connected, go to the Main AI Hub in your dashboard. You'll see a list of available AI agents, such as the CRO Optimizer, Google Ads Landing Page Agent, Website Translation Agent, and Bot Protection Agent. Click to activate the agents you want.

Use the Configuration section to adjust parameters for each agent. For example, you can control which pages an agent runs on or how aggressive the copy changes are.

Step 6: Verify the Integration Works

To confirm everything is working:

1. Open your website in a normal browser window.
2. Visit a page where you activated an agent.
3. Check that the page loads normally and the content looks correct.
4. In your SeaText dashboard, confirm the agent shows as active.
5. If you activated the Translation Agent, test a page in a different language.

SeaText provides an initial round of automatic translations and variants for testing. Log in, go to "Variants Edit" in the left panel, and select the URL and language you want to review. You can manually edit translations there.

Common Mistake: Using a Development URL

The most common integration mistake is testing on localhost or a dynamic development domain. SeaText restricts development URLs for security reasons and may not reliably associate traffic with your account. Always use a valid, real domain—even for testing. If you need a staging environment, use a real subdomain like staging.yoursite.com and create a separate SeaText account for it.

Key Facts About SeaText JavaScript Integration

How the JavaScript Integration Works

The SeaText script is a lightweight loader that connects your site to SeaText's AI engine. When a visitor lands on your page, the script sends page context to SeaText. The AI then decides whether to adjust headlines, offers, product blocks, or CTAs based on the visitor's source, keyword, or language.

For example, if someone clicks a Google ad for "cheap flats to rent," the Google Ads Landing Page Agent can rewrite the page headline to match that search. The script handles this in real time before the page fully renders.

Because the script is inert until activated, you can install it safely without changing your live site. Activation happens from your dashboard, not from the script itself.

Limitations and When This Advice Doesn't Apply

This integration method assumes you have access to your site's HTML or a plugin that allows custom scripts. If your platform blocks custom JavaScript—some strict enterprise CMS setups do—you'll need to work with your IT team or use a supported plugin.

SeaText does not support localhost or dynamic development domains. If your only testing environment is local, you'll need a real staging domain.

Each SeaText account is tied to one primary URL. If you run multiple separate websites, you need one account per website. This is not a multi-site license.

Frequently Asked Questions

How long does SeaText take to activate after adding the script?

Visit or refresh your site several times and stay on a page for at least 40 seconds. Then wait at least five minutes. Your website name should appear next to the SeaText logo in the dashboard. If not after 10 minutes, contact support.

Can I use SeaText on a localhost development site?

No. Development URLs like localhost are restricted for security reasons. Use a valid, real domain. Dynamic development domains may also fail because SeaText can't reliably associate traffic with your account.

Do I need a separate SeaText account for each domain?

Yes. Each account is linked to a single primary URL. If you use a development domain and a production domain, create separate accounts for each.

What happens if I paste the script but don't activate any agents?

Nothing changes on your site. The script remains inert until you activate agents from the Main AI Hub. Your content stays exactly as it was.

Can I edit the JavaScript snippet?

No. Copy the snippet exactly as provided. Modifying it can break the integration or prevent activation.

How do I know the integration is working?

Check your SeaText dashboard. Your website name should appear next to the SeaText logo. You can also test an activated agent—for example, view a translated page or check if a headline changes for a specific ad keyword.
